器件型号： TDA4VM-Q1
Thread： TDA4VM 中讨论的其他器件

你（们）好
TDA4VM SDK9.2

我遇到了一个问题、TIDLRT_create(prms, &handle)tidl_model_destroy在每次迭代中循环至、然后循环至。
  • 何时ulimit -n设置为 1024 、该进程在之后崩溃/失败 92 次迭代 。
  • 何时ulimit -n设置为 65536 、该进程可以运行更多的迭代。
似乎存在资源泄漏（可能是文件描述符）、这会阻止进程以较低的限制无限期运行。
我的问题是：
  1. 为什么即使我正在调用销毁功能、也会发生此泄漏？
  2. 是否有办法解决或解决此泄漏问题、以允许无限循环？

    尊敬的 Yang：

    您能否在现有 SDK 演示上创建任何测试用例以重新创建问题？

    我已修改测试应用程序 TI_DEVICE_ARMv8_TEST_dl_algo_host_rt.out、将 TIDLRT_create  () 和 TIDLRT_DELETE () 调用约 1000 次、并且无法重现问题、更改如下。
